1. GSM BASED ADVERTISING DISPLAY SYSTEM USING
LED PANEL
ABSTRACT
In this project we are using GSM modem for communication and LED panel for advertising.
GSM means Global System for Mobile communications. It is a hugely successful wireless
technology now a day’s it has become the world's fastest growing communications
technology. GSM is an open, digital cellular technology used for transmitting mobile voice
and data services. The GSM operates in the 900MHz and 1.8GHz bands GSM supports data
transfer speeds of up to 9.6 kbps, allowing the transmission of basic data services such as
SMS.
The project constitutes a microcontroller, GSM modem & LED panel. The particular person
needs to send a SMS to the GSM modem. The GSM modem will be received by the SMS it
will send the information to the microcontroller, the controller converts the received message
and it will display message on the LED panel.
